Abstract

Plastic is widely used in Indonesia, but its non-biodegradable nature causes accumulation and environmental pollution. As a solution, more eco-friendly bioplastics have been developed. This study aims to produce and analyze pudding spoon molds made from Polylactic Acid (PLA) and cassava starch using the injection molding method. The process began with product and mold design using Autodesk Fusion 360 with product dimensions of 125.5 × 25.2 × 2 mm and mold dimensions of 132 × 60 × 35.6 mm. Mold Flow simulation was conducted to analyze parameters such as fill confidence, visual defects, warpage, air traps, and deflection. The mold was manufactured using CNC machining with aluminum 5052 material. The PLA and cassava starch mixtures were varied, heated at a mold temperature of 160 °C and injection temperature of 190 °C, with a cooling time of approximately 5 minutes. The comparison between simulation and actual results showed dimensional differences for each material variation. The largest deviation occurred at a ratio of 40% PLA and 60% cassava starch, reaching 14.9%, while the best result was obtained at a ratio of 50% PLA and 50% cassava starch with only 0.72% deviation from the initial design. This study indicates that material composition significantly affects the dimensional quality of bioplastic products produced through the injection molding process.

Abstract

One of the key elements in making high-quality sponge cake batter is consistent and precise mixing, ensuring all ingredients are well-blended and producing the air bubbles necessary for softness. The aim of this machine redesign was to overcome the limitations of the previous design by using a multi-stage pulley. By redesigning the machine, it can be tailored to more specific operational needs, improve product quality, and minimize wasted time. To achieve this goal, the sponge cake mixer, which previously used a fixed-size pulley system, was updated to be more efficient in regulating rotation speed. Therefore, research was conducted by replacing the pulley size variations with a 5-inch diameter with 840 rpm, 6 inches with 700 rpm, and 7 inches with 600 rpm. During the testing process, the dough was mixed and the time required until the dough was ready was recorded.Based on the results of the trial using a multi-level pulley, it was found that the average time for mixing sponge cake batter with a 5-inch pulley produced an average time of 37 minutes, while a 6-inch pulley produced an average time of 46 minutes, and for a 7-inch pulley produced an average time of 55 minutes. A 5-inch diameter pulley is the appropriate size for use in a redesigned sponge cake batter mixer machine because it produces the fastest mixing time, which is an average of 37 minutes, with a rotation speed of 840 rpm. This pulley size is able to increase the efficiency of production time without reducing the quality of the dough mixing results

Abstract

Waste management issues have become a national concern with serious impacts on social, economic, health, and environmental aspects. The low level of awareness among communities and industrial actors in managing waste has contributed to environmental pollution. Along with the development of cities and regions, the volume of waste including used lubricating oil from vehicles and motorized machinery continues to increase. Not only in large cities, but small workshops in rural areas also generate used oil waste, resulting in its widespread distribution across Indonesia. This study employed a field experimental method. The approach was conducted by testing fuel mixture compositions in a stove fueled by used oil to observe the effect of fuel composition on the combustion process. The results indicate that variations in fuel composition significantly affect combustion quality. In the mixture of used oil and kerosene, a ratio of 40:60 produced the highest flame temperature of 378°C, the fastest cooking time of 4.05 minutes, and a blue flame indicating more optimal combustion. In contrast, the 60:40 mixture resulted in the lowest temperature of 318°C, the longest cooking time of 5.07 minutes, and a predominantly orange flame. For the mixture of used oil and biodiesel (biosolar), the 40:60 ratio also demonstrated the best performance, achieving the highest flame temperature of 380°C, the fastest cooking time of 3.52 minutes, and a stable blue flame.

Abstract

Penelitian ini bertujuan untuk mengkaji hubungan kekerabatan antara Bahasa Jawa Lampung Timur (BJLT) dan Bahasa Minang Riau (BMR) dalam kerangka linguistik komparatif. Kedua bahasa tersebut menarik untuk dikaji karena sama-sama berkembang di luar wilayah asal penuturnya, sehingga berpotensi mengalami dinamika kebahasaan yang berbeda. Penelitian ini menggunakan pendekatan deskriptif dengan metode komparatif yang memadukan analisis kualitatif dan kuantitatif. Data penelitian berupa 100 kosakata dasar Swadesh yang diperoleh dari penutur asli masing-masing bahasa melalui teknik simak dan cakap. Hasil penelitian menunjukkan bahwa BJLT dan BMR memiliki 17 kosakata kerabat dengan persentase kekerabatan sebesar 17%. Berdasarkan kriteria leksikostatistik, persentase tersebut menempatkan BJLT dan BMR pada tingkat satu rumpun bahasa. Temuan ini menunjukkan bahwa meskipun berada dalam rumpun bahasa yang sama, kedua bahasa tidak memiliki hubungan kekerabatan yang dekat secara leksikal.

Abstract

Latar Belakang: Anak dan remaja merupakan masa pencarian jati diri. Internet berperan besar bagi kehidupan mereka sehingga paparan pornografi mudah diterima. Oleh sebab itu, internet menjadi salah satu penyebab KSA (Kekerasan Seksual Anak).Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan pemanfaatan media internet dengan sikap siswa terhadap kemampuan dalam antisipasi tindak KSA.Metode: Penelitian ini merupakan studi analitik cross sectional. Populasi target yaitu siswa usia 10-14 tahun, sedangkan populasi terjangkau yaitu seluruh siswa kelas TA PAA Al-Falaah Blunyahgede Yogyakarta. Pengambilan sampel menggunakan Total Sampling sebanyak 34 anak. Penelitian dilakukan pada 8–13 September menggunakan instrumen yang telah diuji validitas dan reliabilitasnya. Analisis data menggunkan uji Spearman ra nk (α = 5%).Hasil: Hasil penelitian menunjukkan bahwa dari 34 siswa PAA AL-Falaah 19 anak 55,88% memanfaatkan media internet tinggi dan 20 anak 58,82% memiliki sikap positif terhadap kemampuan dalam antisipasi tindak KSA. Uji korelasi Spearman Rank menujukkan p value 0,047 < 0,05 dan nilai ρ sebesar 0,344. Artinya ada hubungan pemanfaatan media internet dengan sikap siswa terhadap kemampuan dalam antisipasi tindak KSA dengan kekuatan lemahKesimpulan: Pemanfaatan media internet berhubungan dengan sikap anak terhadap kemampuan dalam antisispasi tindak KSA namun internet juga memiliki dampak positif bagi penggunanya.

Abstract

Latar Belakang: Premenstrual syndrom (PMS) merupakan ketidaknyamanan yang dialami wanita usia produktif menjelang menstruasi akibat mekanisme hormonal yang seringkali mengganggu aktivitas dan produktifitas hariannya. Suplementasi susu kedelai yang mengandung fitoestrogen diharapkan dapat menyeimbangkan kadar hormon estrogen tubuh, sehingga dapat menurunkan ketidaknyamanan PMS.Tujuan: Menganalisis pengaruh pemberian susu kedelai terhadap penurunan keluhan PMS pada remaja.Metode: Desain penelitian ini adalah quasi experiment pre-post with control group design. Subyek penelitian ini adalah siswi SMAN 6 Yogyakarta kelas XI. Teknik pemilihan sampel adalah simple random sampling. Subyek penelitian terbagi atas kelompok perlakuan (mendapatkan suplementasi susu kedelai setiap hari selama fase luteal dalam 1 siklus) dan kelompok kontrol (mendapatkan susu kedelai 1 minggu sekali selama 1 siklus). Susu kedelai yang digunakan sebanyak 300 cc yang mengandung 49,7 mg/L flavonoid. PMS diukur menggunakan Menstrual Health Questionnaire (MHQ). Data yang telah diperoleh dianalisis dengan uji Anova (α=5%).Hasil: Kelompok perlakuan mengalami median penurunan lebih besar dibandingkan kelompok kontrol (median 7,00 vs 6,00) dengan analisis beda penurunan keluhan menstruasi antara kelompok kontrol dan perlakuan yang tidak bermakna (nilai p = 0,951).Kesimpulan: Suplementasi susu kedelai tidak berpengaruh terhadap penurunan keluhan PMS pada remaja.
